  1. 1. Lecture 5 ETE411 :: Semiconductor
  2. 2. Topics • Principles of Quantum Mechanics • Wave particle duality
  3. 3. Principles of Quantum Mechanics • The motion of large objects, such as planets and satellites, can be predicted to a high degree of accuracy using classical theoretical physics based on Newton's laws of motion. But certain experimental results, involving electrons and high-frequency electromagnetic waves, appear to he inconsistent with classical physics. However, these experimental results can be predicted by the principles of quantum mechanics. The quantum mechanical wave theory is the basis for the theory of semiconductor physics.
